NIANUFACTURE OF CARD OR PAPER SHEETS.

SPECIFICATION forming part of Letters Patent No. 767,329, dated August 9, 1904.

Application filed December 17., 1903.

T0 ctt?, whom t 71mg/ concern:

Beit known that I, CHARLES H. CRosIER, a citizen of the United States of America, and a resident of Vest Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Manufacture of Card or Paper Sheets, of which the following is a full, clear, and exact description.

The object of this invention is to produce a paper or cardboard sheet having a mottled or marble-like appearance at its face notwithstanding the fact that the sheet'or sheets making the face or faces of the card or composite sheet are of uniform color throughout the entire substance and area thereof.

The invention consists in a composite sheet or card composed of a body layer of paper and a face layer of paper adherently connected to the body layer, the body layer being of a different color than the face layer and the latter having in different portions thereof different degrees of translucency, whether this latter characteristic be acquired by making the face-constituting sheet of unequal thickness in different places or so treating' the faceconstitutingsheet, which might be of uniform thickness, chemically or otherwise, whereby it has spots or patches distributed throughout its area less opaque than the relatively intermediate spots or patches.

A cardboard sheet of the character described is in a manner illustrated in the accompanying drawings, in which- Figure l is a perspective view, a portion of one of the face-constituting sheets being represented as partially stripped and turned back from the body-constituting layer. Fig. 2 is a sectional view through the thickness of the paper, on a very much enlarged scale, as taken Fig. 3 is a sectional view similar to Fig. 1, designed to represent the provision in the composite sheet of the face layer having a uniform thickness, with, however, varying' degrees of translucency for the acquirement of substantially the same mottled appearance.

In the drawings, A represents the body layer or sheet of paper, and B the face layer, the

latter having at different spots or portions of its area different degrees of semitransparency or translucency, the face layer being of a different color than that of the body layer and stuck thereto by paste or other suitable adhesive.

As most practicably carried out generally the face layer is rendered variabl y translucent, as aforesaid, by having variations in its thickness at diiferent spots distributing throughout its area and, as represented in Fig. 2, the thicker portions a being more opaque or less translucent than the thinner portions I), so th at the color of the body layer A, which is different from that of the face layer, may be more or less visible at the face of the sheet through the less opaque portions.

The card may have a back face-sheet B2 as ,well as a front face-sheet B and of the same character.

Any colors or combinations thereof may be observed in the manufacture or selection of the sheets which are combined to make the new card. For instance, the body-sheet may be very dark, as black, slate, gray, &c., and the face sheet or sheets may be white or of any color or tint strongly contrasting with that of the body-sheet.

In Fig. 3 the face sheet or sheets are represented for the acquirement of substantially the same visual effect by being made of uniform thickness having opaque spots a2 and relatively intermediate semitransparent spots b2 therein, which may be produced by subjecting different portions of the sheet of paper to the action of chemicals, which, without in any manner coloring the sheet, makes a multiplicity of segregated small areas therein much more translucent than the commingled areas not treated.

I am of course aware that paper sheets have been produced having mottled, marbled, or variegated appearance produced by the employment of colorl either intimately incorporated in the ber of the paper in the manufacture thereof or afterward applied on the surface thereof; but this invention is in no wise dependent on any such method of production.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, isv

l. A Card or comp osite sheet consisting of 5 a body layer of paper, and a face layer of paper, adherently connected thereto, the body layer being` of a different Color than the face layer, and the latter having, in different portions thereof, diierent degrees of translu- IO eeney.
